Precise Rack Positioning of Rack Feeders in High-Bay Warehouses with Vision Sensors

Heavy goods and fluctuating temperatures can affect the dimensional accuracy of metal structures in high-bay warehouses. In order for the rack feeders (RF) to be able to store and unload containers precisely over the alleys, which are up to 40 m high, precise rack positioning is necessary. For this purpose, a vision sensor with external lighting is mounted on the rack feeder on each side, which enables precise positioning via hole detection on the metal struts in the X/Y direction. The vision sensor detects holes of different sizes in single and double depth using a pattern matching software module.
